Windows Vista don't recognize camera's HDD - unknown USB device. When I connect camera in PC whith Windows XP - No problem. Help with USB drivers for Vista. My camera - JVC GZ-MG155

It is a "plug-and-play" device, and Windows XP/Vista/7 are "plug-and-play-aware" systems.
So, just connect it, and Windows should recognize it.

Are you getting any error-messages?
What is happening?
What is not happening?

Forget the drivers...use a card reader.

When installing XP or Vista you get the option to load third party drivers for unknown devices. I think it's F6 just after the start of any version of Windows, once you press this you will have to supply the drivers for the Windows installation. This will make Windows recognise the hdd from then on.

You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.

To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.

unknow just means it dose not have a driver list for the device. go on their web paged for driver from the device web site. and install them from there.

then i think its nt compatiable with vista

to connect yo,r pen in usb port and anotner one solution is to uninstal your usb drivers in yo,r devicemanager and restart your system then connect your pen

Here is the solution for pen drive (you are must to have got acces to
Windows XP installed drive):
- copy usbstor.inf and usbstor.sys placed in WinXP folders (Windows\INF and
Windows\system32\drivers) on the some location on your disk.
- plug in device with Vista running
- when it is not recognized place to location where you saved these two
files above
- when you vista recognize mass storage device you will get information
about inproper INF section, and the second device will be unknown in your
device manager
- try to actualize driver for unknown device and point Vista to find driver
into your c:\windowsvistadir\ [x] with subdirectories

You should download the driver for Windows XP, unzip it (if not specified otherwise C:\temp\cs330_XP).

I guess that if you say the camera doesn't work it means you already tried to connect it to the USB in your computer. If so, right-click on "My Computer" and click on "Manage". Go to "Device Manager (under "System Tools"). You should see there a device named "Unknown Device". Double click on it and go to the Driver tab. click "Update driver..." and select "Browse my computer for driver software". Now, select the location you unzipped the driver to (as said before, usually C:\temp\cs330_XP) and click next until windows will try to install the driver. This can take from a few seconds to a few minutes. After a while (for me it took about 2.5 minutes so be patient) windows should say the installation was succesful.
Enjoy :-)
